As shown in FIGS. 1 to 3, the grommet A includes, for example, a resin-made high-strength reinforcing inner 1, a resin-made inner lid 10, and a rubber-made, low-rigidity, low-rigidity and flexible grommet body 20. It consists of. The vehicle body panel 30 has an elliptical grommet mounting hole 31, and the grommet A of this embodiment is mounted in the grommet mounting hole 31.

  The reinforcing inner 1 is formed of a cylindrical body having an elliptical cross section, and is formed in a fitting portion 2 that is fitted into the grommet mounting hole 31 of the vehicle body panel 30 by insertion, and is formed in the fitting portion 2, and an electric wire (see FIG. (Not shown) through which the electric wire penetrating part 3 passes, and a pair of lever parts 4 and 5 arranged at positions outside the electric wire penetrating part 3 and behind the fitting part 2. The fitting portion 2 is provided with a locking claw 2 a that can be locked by being inserted into the grommet mounting hole 31 of the vehicle body panel 30. A flange portion 2b is provided at the rear end of the fitting portion 2 in the insertion direction so as to project to the outer periphery. Each lever part 4 and 5 has the latching | locking part 4a, 5a latched in each lever through-hole 11 and 12 mentioned later while projecting back in the insertion direction from the collar part 2b.

  The inner lid 10 includes a pair of lever through holes 11 and 12 through which the pair of lever parts 4 and 5 are penetrated, a lid side pressing part 13 provided at a position between the pair of lever through holes 11 and 12, It has the holding | maintenance part 14 hold | maintained by the collar part 2b and the latching | locking parts 4a and 5a of the lever parts 4 and 5, and the electric wire fixing | fixed part 15 protruded from the holding | maintenance part 14 ahead of insertion.

  The pair of lever portions 4 and 5 and the pair of lever through holes 11 and 12 are set to dimensions that cannot be penetrated by different combinations. Specifically, the length L1 of the one lever portion 4 and the length L3 of the lever through hole 11 are set smaller than the length L2 of the other lever portion 5 and the length L4 of the lever through hole 12 (L1). <L2, L3 <L4) and the length L2 of the other lever portion 5 is set larger than the length L3 of the one lever through hole 11 (L1 <L3 <L2 <L4).

  As shown in FIGS. 4A and 4B, the electric wire fixing portion 15 has a rod shape, and is arranged in the electric wire through hole 31 in a through state when assembled to the reinforcing inner 1. The electric wire fixing part 15 is set to a dimension that protrudes by an L dimension from the fitting part 2 of the reinforcing inner 1 when assembled to the reinforcing inner 1. The L dimension is an appropriate dimension for fixing the electric wire W to the electric wire fixing portion 15 with the constraining tape (or constraining band) 40. Thereby, if the electric wire W is fixed, it will be in the positional relationship by which the inner cover body 10 is assembled | attached to the reinforcement inner 1 reliably.

  The grommet main body 20 is provided so as to cover the pair of lever portions 4 and 5 of the reinforcing inner 1 and the lid-side pressing portion 13 of the inner lid body 10, and a pair of electric wire penetrating portions 21 through which an electric wire (not shown) passes. The first operation units 22 and 23 and the second operation unit 24 are provided. The pair of first operating portions 22 and 23 are disposed at locations corresponding to the pair of lever portions 4 and 5 and can press the pair of lever portions 4 and 5. The second operation unit 24 is disposed between the pair of first operation units 22 and 23 and can be disposed at a location corresponding to the lid-side pressing unit 13 to press the lid-side pressing unit 13.

  Further, the grommet body 20 has a hollow flange portion 25 that protrudes to the outer periphery and accommodates the flange portion 2b of the reinforcing inner 1 and the holding portion 14 of the inner lid body 10, and at the front end in the insertion direction of the hollow flange portion 25, A lip portion 26 that elastically contacts the surface of the vehicle body panel 30 is provided.

  In the above configuration, when the inner lid body 10 is incorporated into the reinforcing inner 1 through the electric wire W, the lever portions 4 and 5 of the reinforcing inner 1 are inserted into the lever through holes 11 and 12 of the inner lid body 10 to hold the holding portion 14. When abutting against the flange portion 2 b of the reinforcing inner 1, the locking portions 4 a and 5 a of the lever portions 4 and 5 are locked to the holding portion 14. As a result, the holding portion 14 is sandwiched between the collar portion 2 b and the locking portions 4 a and 5 a of the lever portions 4 and 5, so that the inner lid body 10 is assembled to the reinforcing inner 1. Next, the constraining tape 40 is wound around the outer periphery of the electric wire fixing portion 15 and the electric wire W of the inner lid body 10, and the electric wire W is fixed to an integral part of the reinforcing inner 1 and the inner lid body 10. Thereafter, the grommet body 20 is assembled to the reinforcing inner 1. In addition, the operation | work which fixes the electric wire W with the restraint tape 40 may be after the operation | work which attaches the grommet main body 20 to the reinforcement inner 1. FIG.

  After assembling the reinforcing inner 1, the inner lid 10, and the grommet main body 20 in this way, the fitting portion 2 of the reinforcing inner 1 is inserted into the grommet mounting hole 31 of the vehicle body panel 30, and is indicated by the arrow F1 in FIG. As described above, when the operator presses the pair of first operation parts 22 and 23 of the grommet body 20 with a finger in the insertion direction, the grommet body 20 is elastically deformed and the reinforcing inner 1 is inserted through the first operation parts 22 and 23. Since the pair of lever portions 4 and 5 are pressed, the locking claw 2a of the fitting portion 2 passes through the grommet mounting hole 31 and is locked in the grommet mounting hole 31, and the fitting portion 2 is in the grommet mounting hole. 31 is fitted.

  Further, when the fitting portion 2 of the reinforcing inner 1 is inserted into the grommet mounting hole 31 of the vehicle body panel 30 and the operator presses the second operation portion 24 of the grommet body 20 with a finger as shown by an arrow F2 in FIG. Since the grommet body 20 is elastically deformed and the lid side pressing portion 13 of the inner lid body 10 is pressed via the second operation portion 24, the reinforcing inner 1 is pressed in the insertion direction via the inner lid body 10. . As a result, the locking claw 2 a of the fitting portion 2 passes through the grommet mounting hole 31 and is locked to the grommet mounting hole 31, and the fitting portion 2 is fitted to the grommet mounting hole 31.

  Next, when the reinforcing inner 1 is removed from the grommet mounting hole 31 of the vehicle body panel 30, the pair of lever portions 4, 5 are pressed by pressing the pair of lever portions 4, 5 from both sides through the grommet body 20 toward each other. Are inclined inward and the fitting state between the fitting portion 2 and the grommet mounting hole 31 is released, so that the reinforcing inner 1 is detached from the grommet mounting hole 31 of the vehicle body panel 30. Further, when the pair of lever portions 4 and 5 are tilted inward and moved through the lever through holes 11 and 12 of the inner lid body 10 to reach the moving end portion, the pair of lever portions 4 and 5 are tilted. Therefore, it is possible to prevent the pair of lever portions 4 and 5 from being deformed.

  Since the reinforcing inner 1 can be fitted into the grommet mounting hole 31 by pressing the second operating portion 24 of the grommet body 20, the reinforcing inner 1 can be attached to the grommet even when the pair of first operating portions 22 and 23 cannot be pressed simultaneously. The hole 31 can be fitted. Therefore, even when the work space for attaching the grommet 1 is narrow, the grommet 1 can be easily attached to the grommet attaching hole 31.

  The lever portions 4 and 5 are provided with locking portions 4a and 5a for locking to the lever through holes 11 and 12, respectively. Accordingly, when the inner lid body 10 is incorporated into the reinforcing inner 1, the inner lid body 10 is assembled to the reinforcing inner 1 via the holding portion 14, and therefore the reinforcing inner 1 and the inner lid body 10 become an integral part, and the vehicle body panel 30 Thus, it is possible to prevent a problem that the inner lid body 10 is dropped from the reinforcing inner 1 at the time of attachment work.

  The reinforcing inner 1 and the inner lid 10 are set to dimensions that cannot be penetrated by different combinations, and the inner lid 10 can only be attached to the reinforcing inner 1 in an appropriate direction, so that the inner lid 10 can be prevented from being reversed.

  The inner lid 10 has a wire fixing portion 15. Therefore, as shown in FIGS. 4A and 4B, the inner lid 10 is assembled to the reinforcing inner 1, and the electric wire W is fixed to the inner lid 10 with the restraining tape 40, so that the electric wire W By checking whether or not the lid body 10 is fixed, it is possible to simultaneously check whether or not the inner lid body 10 is securely attached to the reinforcing inner 1. This is because, when the inner lid 10 is not securely assembled to the reinforcing inner 1, when the electric wire W is pulled, the inner lid 10 is detached from the reinforcing inner 1, and only the inner lid 10 moves.

  That is, as shown in FIGS. 5A and 5B, when the wire fixing portion 15A is provided on the reinforcing inner 1A, the reinforcing inner 1A can be checked even if the wire W is fixed to the reinforcing inner 1A. It is not possible to recognize whether or not the inner lid body 10A is securely assembled. Therefore, it is necessary to perform a double check of the fixing check of the electric wire W and the assembly check of the inner members. On the other hand, in the present invention, as described above, one check is sufficient, and the check work can be shortened.
